Description
Source selection (see Terms and abbreviations
Displays the speed measured by the Backspin Speed
Observer function.
Observer speed measured.
Displays status word of the functions controlling ESP specific
start/stop logic.
Controls frequency/speed reference settings of a drive.
See section Underload and overload protection
Defines the source for the speed reference.
The unit (Hz or rpm) of the speed input is determined with
parameter 19.20 Scalar control reference
Note: If the input reference has a custom scaling, then it
should be explicitly set with parameter
scaler.
